Qffwevzzm i 04177711135. Modzhe Patented June 7, i932 UNITED, STATES PATENT OFFICE ARTHUR B. MODINE, OF RACIN'E, WISCONSIN, ASSIGNOR TO MODINE MIANUFACTURING COMPANY, OF RACINE, WISCONSIN, A CORPORATION OF WISCONSIN' HEATING DEVICE Application filed November 15, 1928.. Serial No. 319583.

My invention relates to improvements in heating devices and more particularly to heating devices comprising radiator units which fr; provided with cabinet housings or the One of the objects of the invention is to inv termittently increase the normal radiating .a cabinet in a capacity of a heating unit whereby the unit is enabled to meet peak demands above or requirements which exceed the predetermined normal capacity of the unit.

Another object is to diminish the time normally required by a heating unit to heat a room of a given size.

Stillanother object is to provide for discharging vertically moving air currents from plurality of horizontal (line tions.

It is frequently desirable to provide a horizontal radiator with a fan, eflicient operation of which makes it desirable that thefan be positioned immediatelybelow or above the radiator and that the fan. be mounted on a vertical shaft. The combination of such a fan with a horizontal'motorrathertnan a vertical motor is desirable, and a further object of the invention is to provide an improved operative connection between a horizontal motor and a vertical fan. 7

Still another object isto provide improved instrumentalities whereby the deflection, di-

, rection andiiischarge of the heated air arising from the radiator unit can be efliciently controlled in accordance with the require-' and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts: a

Fig. 1 is a sectional view through a cabinet containing a radiator unit and a motor operated fan;

Fig. 2 is av View along the line 22 of Fig. 1; Fig. 3 is a sectional elevational view along theline 33 of Fig. 1;

Fig. 4 isa view illustrating an alternative embodiment of my invention which is taken along the line 4 4 of Fig. 5; and

F ig; 5 is a view along the line 5 5 of Fig. 4. Referring now to the drawings, the numerals 10 and 11 indicate a pair of spaced apart horizontally extending radiator units. I The radiator units 10 and 11 areeach supplied with heating fluid which comes through a main feed pipe 12 and branch feed pipes 13. A main vent pipe 15 and a pair of branch vent pipes 14 provide a discharge outlet for the fluid after it passes through the radiator units 10 and 11. Each of the radiator units 10 and 11 comprise a pair of header tanks 16 connected by a plurality of tubes 17. The

tubes 17 are positioned in a plurality of transversely extending perforated-plates or fins 18 which act as spacers for the tubes.

Theradi'ator units are shown as positioned in a cabinet 23. having two oppositely positioned side walls 24each provided with an air outlet grille 26. A plurality of outward ly and downwardly extending battens 0r vanes 27 extend longitudinally of the grilles 26 for a purpose hereinafter more particularly described. The lower portions of the side walls 24; are each equipped with a sieve structure 28. The sieve structures 28 provide entrances for the air and serve to strain and separate the dust particles contained there-J in before the air passes through the radiator unit.

For the purpose of accelerating the movement of air through the radiator unit, I have provided a fan 30 which is mounted on a vertical shaft 33 and is operated by ahorizontal motor 31. I have shown the motor 31 as horizontal rather than vertical. although the invention is equally adapted 'for'use with a vertical motor. The fan 30 and the motor 31 are both supported by a. base 32. In Fig. 1, I have shown the fan 30 as mountedabove the radiator units 10 and 11. The fan30 is actuated by the vertical shaft 33 which is positioned between the units 10 and 11. The shaft 33 is held in its vertical position by a brace member 34 which is shown as integralsieves 28 and upwardly through the radiator units 10 and 11. A. rectangular shaped partition or frame 37 having a circular opening 38 encloses the radiator units so as to confine the passage of air to the circular area in which the fan 30 rotates.

In order that the heated air coming from the fan 30 may be discharged and generally distributed throughout the room, I have provided in the upper portion of thecabinet 23 an instrumentality 40 which is made u of a pair of arcuate shaped plates 41. The plates 41 are oppositely curved upwardly and outwardly, havingtheir inneredges vertical and connected at the middle of the cabinet 23.

The outer edges of the plates terminating inthe side walls 24 of the C bin imme i y jacent the radiator unit, providing means to i above the grille openings 26. The plates 41 take a general horizontal direction at their intersection with the side walls 24-. The fan 30 drives the air currents with a considerable.

velocity against the arcuate plates 41 with the result that the column ofair is directed horizontally through the grilles 26 and leaves the cabinet in a generally horizontal direction with a considerable velocity.

Figs. 4 and 5 illustrate an alternative embodiment' of the invention in which the upper portion of the cabinet-'23 differs from the embodiment shown in Figs. 1 and 3, in that it' has grilles 26 in all four of its side walls 24. Each ofthe four grilles 26 is equipped with vanes 27. An instrumentality 42 is positioned to deflect the rising air currents outwardly through the grilles 26. The

. instrumentality 42 is constructed of four arcuate shaped plates 43 which curve upwardly and outwardly to form an inverted pyramid having curved sidewalls. The plates 43 are of generally triangular shape meeting at the center of the cabinet 26, and

have their opposite base edges terminating. in the side walls 24' of the cabinet at the top of the grilles 26. The plates 43 each take a generally horizontal direction at their intersection with the side walls 24, so that the air is driven against the vanes 27 in a generally horizontal direction.-

In practice I find that devices of this ldnd which are of sufficient size'to heat lofts and factory units are necessarily of considerable height. In such cases the heated air may be discharged from the cabinet at a point someseve'n oreight feetabove the floor, and in order that thelower spaces of the room .may beproperly heated I have provided the vanes or batten plates 27 which tend to direct the air downwardly and outwardly as it leaves the grilles 26.

- Thus it will be seen that I have provided a heating apparatus which is adapted to heat rooms of all sizes and especially to'heat large the room.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limit ing myself to the exact form", construction,

arrangement and combination of parts heren shown and descrlbed or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

A heating device comprising an 'open endedcabinet containing a radiator unit supported by said cabinet, a fan positioned adaccelerate vertical movement of air through the unit, an annulus extending from the radiator unit and. surrounding the fan, said cabinet having a plurality of outlet openings 2. A heating device comprising a cabinetv containing a radiator unit, a fanproviding means for causing movement of air vertically through said unit, a memben cooperating with the fan and radiator unit providing means facilitating said movement, a plural- 'ity of openings forming an outlet for'the heated air, said openings forming a substantially continuous grille in the perimeter of the cabinet above said member, and an instrumentality adaptedto discharge the air horizontally through said openings. I

In testimony whereof, I have hereunto signed my name.
